Base Strength Benefits HumanSport® strengthens individual muscle groups with outside stabilization, helping prepare and build the muscles you’ll use in training, while developing your flexibility and stability to ensure you’re ready for the harder work to come. Core Stabilization Benefits HumanSport’s integration of core stabilization and multi-planar movements helps strengthen core muscles in your body, so you’ll achieve overall strength and balance – enabling you to perform better and get more out of individual muscle group workouts.

Instead, its dynamic movement trains your muscles from an infinite number of angles for a broader range of movement, strength, flexibility and balance.
